Hey Don,

It looks like Thule unfortunately discontinued the 43215 U-bolt and there isn't a replacement available so your best option would be to pick up new U-bolts from your local hardware store. If you don't still have a U-bolt to measure you can just measure the holes, their spacing and the gauge how much length you'll need to pick out a new U-bolt that will fit. They should also have some compatible knobs with nuts built into them so that you can tighten the U-bolts down, securing the cargo box.

Hey Don, what ended up working once you measured for new U-bolts to replace the Thule ones? Sharing how they fit could help others looking for a similar solution.

I think that the U bolts that Thule used were proprietary oones - unique size. I bought one from a supplier that said theyi would fif. They didn't . But I finally bent them to the size that I needed. Works now.\ Thanks for checking back.\ Don Horan
